Was gonna say, "Doesn't seem like a money-rich operation." From what I can glean from Google Translate this may not be an official CGM video (and the visuals aren't as crisp as the street performance this lifts from).

*.CGM엔터테인먼트에서 만든 뮤직비디오가 아닌
개인이 만든 뮤직비디오임을 먼저 알립니다.

신입걸그룹 플래쉬의 뮤직비디오를 만들어 보았습니다.
즐거운 감상해주시고 플래쉬 많은 응원 부탁드리겠습니다.^^

Which Google Translate renders as:

Not made ​​music video * CGM Entertainment from
First notifies the individual that made ​​music video.

I tried to make a music video of the new girl group flash
Haejusigo Flash enjoyable watching a lot of support in favor happy ^ ^

But the person who posts as TheCGMEnterTainment did link it with a "like" on his or her site.
